Deciding the type of catering that will suit your event is really important.
Here we talk about buffets which are very popular.
Buffet Style Catering
Food stations are set up on long tables where guests can walk along and serve themselves. Another option is to have servers stationed behind the buffet table serving each dish. A buffet-style event is usually considered the most casual style of meal service.
Pros: Fewer servers are needed with a buffet reception, which means you may save some money on your catering-staff charges (though you still need staffer to tend to the buffet, and waiters to provide water and wine to the tables). Buffets make it easier and more cost effective to provide guests with a variety of choices, which is helpful since many people have so many types of allergies and dietary restrictions. This service style also promotes mingling and interacting among guests.
Cons: Since each table will have to wait their turn to head to the buffet, it may take a while for all guests to receive their food; queues may also form. You also might have to rent linens, chaffing dishes, and serving pieces. Guests may have to serve themselves and carry their own plates, which may not be as elegant as you would like. Buffets also require larger quantities of food since people tend to eat more when they serve themselves, which will add to your food costs.
